This invention relates to looms of the type ordinarily used for weavingAxmmster carpets and similar fabrics and is concerned more particularlywith a new device for carrying the yarns to be used in making the piletufts.

In looms of this type, as heretofore commonly constructed, the pileyarns are carried on a large number of spools, each of which is mountedin a frame slung between chains which pass over sprocket wheelssupported in the frame of the loom. Each spool carries a plurality ofyarns arranged tosupply one row of tufts across the fabric and the thechains are moved tobring the spools one after another into a positionabove the weaving mechanism where yarn is drawn from the spools andincorporated in the fabric. When wide fabrics are being woven, eachspool may be replaced by several axially aligned spools all carried inthe same frame. The frames which carry the spools are usually providedwith brackets for supporting the spools, and have holes or tubes throughwhich the yarns are presented to the weaving point and brakes or tensiondevices to prevent the spools from rotating too freely and unwindingexcess y Difficulty is encountered with the construction described onaccount of the fact that a large number of yarns are carried on eachspool and, if the brake on a spool gets out of order, the yarn overrunsand a tangle involving a large number of yarns results. Also, lack ofproper tension on the yarn causes the fabric to be imperfect andunsatisfactory. Another objectionable feature of the former constructionis that in order to remove or replace a single pile yarn, it isnecessary to remove a whole spool and all of the group of yarns carriedby it, and replace it with a properly wound spool, and this involvesthreading all the yarns of the new spool through the holes or tubes ofthe carrier. Since the yarns on a single spool are usually of severaldifferent colors in accordance with a pattern, a chan e in the patternrequires that all the spools be removed and completely rewound.

The present invention is accordingly directed to the provision of animproved pile yarn carrier for a loom, in which there are no spools,supporting brackets, or spool tensioning devices and in which the pileyarns are carried in separate packages so that a single supply of yarnmay be replenished or taken from the machine and replaced by anotherwithout disturbing the other yarn supplies in the carrier. The newconstruction also eliminates the necessity of winding spools to conformtothe design to be woven, and the yarn packages used in the new carrierhold more yarn than the spools and hence the loom may run longer withoutreplenishing the yarn supply.

In one embodiment of the principles ofthe invention, the carriermechanism includes a plurality of frames which carry magazines, each ofwhich holds a plurality of yarn packages or cops which can be removed orreplaced without lnterfering with any other of the pile yarns. Thecarrier is suspended between chains as before. In withdrawing the yarnfrom the cops, the cops are not rotated and hence overrunning is notencountered.

For an illustration ofthe manner in which I prefer to build my improvedcarrier, reference may be had to the accompanying drawings, in which: I
